摘要
某炼厂重整装置在开工过程中,装置外送系统的火炬放空线,由于装置开工初期系统晃电,造成装置内设备超压、安全阀起跳,从而造成装置外送系统的火炬放空线前后发生3次振动。经过管道系统分析及现场支架排查,利用应力分析软件CAESARⅡ模拟计算,分析事故原因,采取措施,有效解决了现场振动问题,为今后此类管线设计积累经验并提供借鉴。
During the start-up of the CCR unit in a refinery, discontinuous power supply at the initial stage of startup led to equipment overpressure and the opening of safety valves.As a result,the main flare line vibrated three times.CAESARⅡ,piping analysis software,was used to analyze the piping system and check the brackets.By analyzing the reasons and taking some measures,the vibration problem was solved,and experiences were accumulated for the future design of such pipelines.
